CHARLES W. HUNT, OF WEST NEW BRIGHTON, NEW YORK.

CABLE RAILWAY.

SPECIFICATION forming part of Letters Patent No. 540,058, dated May 28,18,95.

" Application filed August 24, 1891. Serial No. 403,547. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES W. HUNT, a citizen of the United States,residing at West New Brighton, in the county of Richmond and-State ofNew York, have invented a new and useful Improvement in Gable Railways,of which the following is a specification.

An endless chain or cable has been made use of for drawing a car up anincline on one track or lowering the car down the incline upon anothertrack.

My present invention is made with reference to rendering the trackscompact so as to occupy but little space, one rail of one track beingbetween the two rails of the other track, and with this arrangement thedifierent portions of the chain or cable are central to the respectivetracks, and the approaches to these tracks are either by two separatetracks converging to the aforesaid rails, or by one track and a switch.

My improvement is especially applicable to tracks in factories or yards,to places where there are short lines and grades from one elevation toanother or to places where cars have to be transferred from point topoint, or over bridges, &;c.

In the drawings, Figure 1 is a plan view of my improvement. Fig. 2 is anelevation of the same, and Fig. 3 is an enlarged crosssection on Fig. 1at the line a: m. Fig. 4 is an elevation at the section line :12 m. ofFig. 3, and Figs. 5 and'6 are detailed views at the cross-section linesyy and z 2, respectively, of Fig.4. Figs. 3to 6,inclusive, are in largersize.

or represents the endless cable composed of wire rope or links. I preferlinks of the form shown with notched opposite edges.

The cable a runs over pulleys b, 1), whose shafts are suitably journaledand power is applied to a pulley c on one shaft. The pulleys b, b are ofsufficient width to allow the cable to pass around them, and the cableis of sufficient length for one portion to be brought up to the sameplane as the other portion.

The cable a passes around the respective pulleys b, b and it draws in astraight line from one to the other except where the cable rises, asindicated in Fig. 4:,and passes over a guide roll in one of the guideblocks d and it passes over a similar roller as it descends to the otherpulley (b), and theseguide blocks 01 are placed upon the ties, and thenotches in these 5 5 guide blocks are adapted to guide the respectiveparts of the chain or cable, so that one portion of the chain or cableis central or nearly so between the railsfandf' composing one track, andthe other part of the 6d chainor cable is central or nearly so betweenthe rails 77., h composing. the other track. I have represented by thearrows the trackfif as the up track and the track h, h asthe down track,and the separate tracks z' and l are represented as converging to therails f, f and h, h respectively, and the switch rails m are representedas movable so as to bring either track to coincide with the track it. Ihave represented a car at 0 with a downwardly projecting arm, the end ofwhich is adapted to engage the chain a, such chain being represented asmade of links with heads the car 0 projects downwardly and is central ornearly so in order thatthe end of the arm may engage the proper part ofthe chain as the caris run from the track 7; upon the rails fand isdrawn up by the chain, or as the car may be run over the switch or railsto the track h, h and engage the descending portion of the chain tolower the car down such track to the track 1.

I claim as my invention- The combination with the parallel lines ofrails forming two tracks for cars moving in opposite directions, of anendless cable composed of notched links, pulleys around which the cablepasses and means for driving one of such pulleys and guide blocks havinggrooves or ways for both portions of the cable to lie in while moving inopposite directions, substantially as set forth.

Signed by me this 18th day of August, A. D. 1891.
